Hi Mario,
Are you passing rte_pktmbuf_init as the obj_init argument to rte_mempool_create?
It is called when the mbuf if freed and it will reset the fields. I vaguely
remember I had the same issue at some point and resolved it somehow. This comes
to mind.
Cheers,

Hi Hamid,
I do something similar and works fine. My compiler warning flags are more
pedantic, so I have to ensure those strings are not const literals, but that
doesn?t matter.
I would appreciate an init that takes a struct with options too.

actually I've used:
char* argv[] = {"./build/l2fwd","-c","ff","-n","4", NULL};
(NULL at the end of the list).
Thanks.

Hi,
I'm in need of running an open() function, that is part another program.
open() does many things, the very first of them is rte_eal_init(argv, argc)
I should not receive argc, and argv from main function of the program,
but rather I should produce it myself.

Hi Bruce,
just for dispel
any doubt: if there is one primary process and N secondary processes,
and each process uses only one logical core (they have a coremask equal
to 0x01, 0x02, 0x04, ), I can run at the same time at most "my CPU logical
cores - 1" secondary processes. Is it right?
If you disable mempool caches, you may be able to run more processes than you
have cores, but other issues with duplicate core id's might arise, and your
application performance will suffer as the memory pools will be very
significantly slower.
However, there is no requirement that the lcore_id
Hi all, I'm experimenting some code with DPDK v1.5.0 and I have the following
problem:
I have a thread that receives packets from NIC, once I received a packet I want
to prepend some data to it and I try to do so through the function
rte_pktmbuf_prepend()
then the packet is enqueued in a ring b
